Einfall

Product Introduction

1. Definition: Einfall is a native, capture-first productivity application for macOS, iOS, and iPadOS. Technically, it functions as a system-level input aggregator and action router, leveraging Apple's native frameworks like Share Sheet, Shortcuts, Services, and Widgets to create a ubiquitous capture layer across a user's Apple ecosystem.
2. Core Value Proposition: Einfall exists to solve the cognitive load and friction of "capture" in personal knowledge management (PKM) and task management. Its primary value is providing a zero-friction, always-available system to externalize transient thoughts ("fugitive thoughts") immediately, with the explicit promise of deferred processing, thereby reducing anxiety and preventing idea loss.

Main Features

1. Ubiquitous, Multi-Modal Capture: Einfall integrates deeply into the Apple operating systems to provide over a dozen instant capture entry points. This includes a persistent Mac menu bar icon with a global keyboard shortcut, Home Screen and Lock Screen widgets, the iOS Control Center, system-wide Share Sheet integration, Mac Services (for right-clicking selected text), Siri and Spotlight, and on-device voice transcription. The technical implementation uses standard Apple APIs (App Extensions, WidgetKit, Siri Intents) to ensure low-latency, system-native performance.
2. The Trusted Holding Stream & Simple Action Layer: Captured thoughts land in a simple, reverse-chronological stream—a "trusted holding place" explicitly designed not to be a to-do list. The processing ("Routing") phase involves applying one of 16 plainly named actions to a thought. These actions, such as "Send to Reminders," "Add to Calendar," "Append to File," or "Clean Up with AI," are configurable once (e.g., pointing "Send to Reminders" to a specific list) and then function instantly. The AI clean-up action uses on-device Apple Intelligence, ensuring privacy.
3. External AI Agent Integration via MCP (Model Context Protocol): A technically advanced, optional feature allows Einfall to act as a local server compatible with the open Model Context Protocol. This enables external AI agents (like Claude Code) running on the user's Mac to read the capture stream and execute routing actions in bulk. This runs entirely locally; no data passes through Einfall's servers. It transforms the app from a manual processing tool into an automated pipeline for users who employ AI agents.

Problems Solved

1. Pain Point: The high friction and context-switching cost of capturing a fleeting thought. Traditional workflows require opening a specific app (Notes, Reminders), finding the right list or note, and formatting input, by which time the thought is often lost or its urgency diminished.
2. Target Audience: The primary personas are knowledge workers, creatives, writers, and developers within the Apple ecosystem who experience high volumes of disjointed ideas, tasks, and reference points throughout the day. It is also highly relevant for productivity enthusiasts and PKM (Personal Knowledge Management) practitioners seeking a dedicated "inbox" layer separate from their organization systems.
3. Use Cases: 1) Capturing a meeting idea during a commute via voice widget. 2) Quickly saving a grocery item from the lock screen without unlocking the phone. 3) Selecting a sentence from a webpage and sending it directly to a research note via the Services menu. 4) Using a global hotkey to jot down a code snippet idea while in a development environment. 5) Delegating batch processing of a week's captured items to a local AI agent for categorization and routing.

Unique Advantages

1. Differentiation: Unlike all-in-one note-taking apps (Obsidian, Craft) or task managers (Things, Todoist), Einfall is philosophically and functionally a single-purpose capture and route tool. It avoids feature creep into organization, formatting, or long-term storage, instead excelling at the initial input stage and seamlessly handing off to best-in-class specialized apps. Its pricing model (one-time purchase) also starkly contrasts with the subscription norm for productivity software.
2. Key Innovation: Its commitment to a "Data Not Collected" privacy model, verified by Apple's privacy nutrition label, is a core technical and philosophical innovation. Combined with its use of on-device processing (voice, AI) and iCloud-only sync, it offers a powerful, connected experience with the data sovereignty of a local text file. The optional local MCP server for AI agents is a forward-looking integration that extends functionality without compromising this privacy stance.

Frequently Asked Questions (FAQ)

1. Is Einfall a replacement for Apple Notes or a task manager like Reminders? No, Einfall is a complementary capture layer. It is designed for the initial, frictionless entry of a thought. Its core function is to then send that thought to your preferred destination—be it Apple Notes for elaboration, Reminders for tasks, or Calendar for events. It is the "quick input" front-end to your existing organization systems.
2. How does Einfall's one-time purchase model work compared to subscriptions? Einfall uses a "freemium" model with a one-time unlock fee. Capturing and viewing thoughts is free and unlimited. The first 15 routing actions (sending a thought to another app) are free. After that, a single $29.99 purchase permanently unlocks unlimited routing on all your devices under your Apple ID, including Family Sharing. There is no recurring subscription, ever.
3. Is my data private with Einfall, especially when using the AI features? Yes, absolutely. Einfall has no servers, accounts, or analytics. The "Data Not Collected" label is accurate. Sync uses your private iCloud. Voice capture and the "Clean Up" AI feature run 100% on-device using Apple's frameworks. When using an external AI agent via MCP, the connection is a direct local loop between the agent and the Einfall app on your Mac; no data is transmitted to the internet by Einfall itself.
4. Can I use Einfall on Apple Watch or on Windows/Android? No. Einfall is a native Apple ecosystem app, requiring deep integration with macOS, iOS, and iPadOS APIs. It is not available for Apple Watch at launch, nor for Windows or Android. Its value is maximized for users fully invested in the Apple hardware and software ecosystem.
5. What happens if I don't pay to unlock routing after the 15 free actions? Your capture functionality remains completely free and unlimited. You can continue to capture and review thoughts indefinitely. You simply will not be able to use the "Route" actions (send to other apps) beyond the initial 15. All previously routed items remain in their destination apps.
